Summary

Scientists eager to begin studies on two new types of human stem cells got some good news this week: The National Institutes of Health (NIH) announced that, contrary to what many had feared, U.S. law does not bar federal support for this burgeoning field. Grant money could be approved as early as this fall, according to NIH staffers. Researchers hope to use the cells for studies ranging from basic research on early human development to the development of new technologies for tissue transplantation.
